To all whom it may concern:

Be it known that I, LOUIS MOURAS, a citizen ot' t he French Republic, residing atVesoul, department ot' Haute-Saone, France, have invented certain Improvements in Oesspools and in Means of Draining the Same, of which the following is a specification.

So far as I am aware, there are but three methods nowin use for cleansing and evacuating cesspools. The first is by means of the stationary or fixed drain,whch has the greatinconvenience of giving place to emauations which are injurious, and this drain demands frequent expenditures, and is very disagreeable to manage. The second is by means of the movable drain, the management of which is always annoying and disagreeable. The third is by means Y cfa sewer, in which case a large tlow ot' water in the sewer is required for scouring and for carrying away the heavier matters to the river or sewer-outlet.

By my present invention I have sought to avoid all of the inconveniences of the systems above described. My cesspool is hermetically. closed,and both the inlet and the outlet pipes are sealed in the liquid contents of the cesspool, which hermetically closes them andpre` vents the escape of gases.

In the drawings which serve to illustrate my invention, Figure 1 is a vertical section on line l l in Fig. 2, and Fig. 2 is a plan of my invention in its ordinary form. Fig. 3 is a vertical sectiou ofthe same, but arranged to show the discharge ot' the matters from the cesspool into the sewer above the level of the water therein. Fig. 4 is also a sectional view, showing the discharge-pipe as entering the sewer below the water-level therein, and also showing a provision ou the discharge-pipe to prevent siphoning.

A represents the vault of the cesspool, built with a concrete bottom or bed, D, strong concrete or masonry side walls, E, and a lining, F.

Gr are the flags, which form the covering of the cesspool and the outlet-passage J. These are laid in cement, and their beveled joints L L filled with cement, as shown.

B is the inlet to the cesspool, whereby all the fecal matter, water, dre., enter; and C is the outlet, which is connected'by the passage J with a pipe, I), which leads into a sewer, O.

K indicates in dotted lines in Fig. 1 another route to the sewer.

I is a sealed plug in the cover Gr, which may be removed and the passage J inspected; and H is a man-hole cover, which also tits hermetically, and at which access .may be had to the interior of the vault.

The discharge-pipe C is arranged at or near the top, and the evacuation does not begin until the vault ot' the cesspool is nearly full. Then when any matter enters by the pipe B a corresponding amount of liquid is discharged at C, the level of the duid mass in the vault remaining always the same. It is only liquid, however, that is discharged, this liquid holding in suspension and solution the matters arising from the decomposition and disaggregation of fecal and other matters entering the vault. It is advantageous, therefore, to allow all the surface and waste water to pass into the cesspool on its way to the sewer. With this arrangement the removal of the fecal and other matter is constantly going on, and no gas can possibly escape, as the exits are all sealed. When the discharge-pipe dips into the sewer, as shown in Fig. 1, below the lowwater level therein the discharged matter becomes thoroughly mixed with the waters in the sewer and is borne away without being exposed even to the air in the sewer.

In order to prevent the collection of hard and insoluble substances in the vault-such, for example, as broken glass or china and gravel, which will till up the vaultin course ot time- I provide the means I will now describe.

M is a tray or box with a grated or perforat` ed bottom, which is suspended from the cover Gr by means of suspending links or rods N N, two at each end. rIhis trayis arranged' under the inlet-pipe B, and receives all the solid substances which enter the vault. It is provided with a chain, N', one end ot' which is attached to the tray and the other to a hook at or near the man-hole in the vault-cover. From time to time the cover H is removed and the tray (No Model.)
